A 1,000W PSU is way overkill. 850W is enough to power your system with 2 GPU's. This would be quite a nice setup for gaming on ultra settings for another couple years. Especially if you SLI two of those GPU's. If you don't have a case yet, I'd recommend the Corsair Carbide Series 400R http://www.amazon.com/gp/product/B0055Q7BR4/ref=as_li_q...

Thanks for all of that info. The reason I'm using that particular power supply is that my wife like the "oh so shiny" lights on it, and the 1000w is currently cheaper than the 850w on newegg.
Additionally, I'm gonna be running multiple HDD/SSDs, and a liquid cooling unit. I'd rather have too much than too little
